Abstract
In sample surveys, the problem of non-response is one of the most frequent and widely appearing, whose solution is required to obtain using relevant statistical techniques. The imputation is one such methodology, which uses available data as a source for replacement of missing observations. Two-phase sampling is useful when population parameter of auxiliary information is unknown. This paper presents the use of imputation for dealing with non-responding units in the setup of two-phase sampling. Two different two-phase sampling strategies (sub-sample and independent sample) are compared under imputed data setup. Factor-Type (F-T) estimators are used as tools of imputation and simulation study is performed over multiple samples showing the comparative strength of one over other. First imputation strategy is found better than second whereas second sampling design is better than first. (original abstract)
